ENGLAND.

ELITE-JOINT.

Application filed August 11, 1919.

I. '0 all whom it may concern:

Be it known that we, HARRY JAMES Yarns and CORNELIUS Hnoorn, subjects of the King of Great Britain and Ireland, residing at Essex WVorks, Thimble Mill Lane, Aston, in the city of Birn'lingham, England, have invented certain new and useful Improvements in Flue-Joints, of which the following is a specification.

This invention relates to gas stoves and the like, and has for its object to provide a swivel outlet flue of improved construction.

Referring to the accompanying drawing:

Figure 1 shows a sectional diagram of a swivel outlet flue connecting piece constructed in accordance with this invention.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

In carrying the invention into effect, the burnt gas outlet at the rear of the frame a of the gas stove or the like is formed along its upper side with a curved portion 5, and provided along its lower side with a narrow bar 0 having a curved outer surface. The

outer surfaces of the portion Z) and bar o coincide with an imaginary cylindrical surface drawn as a continuation of the outer surface of the said curved portion 7). The bar 0 is preferably made separate from the portion a and is adjustable thereon toward and away from a horizontal line drawn through the pivots 2'. This adjustment is accomplished by provi-dingthe bar 0 with a down wardly projecting lug 2, which is engaged by a nut :22 mounted on a threaded bolt carried by the part a of the stove. When the nut to is unscrewed the bar 0 may be ad justed vertically and the nut 05 can then be tightened to clamp the bar in its adjusted position.

On this outlet is pivoted a flue connecting piece d which is formed along opposite sides with a pair of curved portions 6, 7, also c0- inciding with the above mentioned cylindrical surface. The curved portion 6 coacts with the upper outer surface 6 of the outlet, while the curved portion f co-acts with the outer surface of the bar 0. The disposition of the curved portions on the connecting piece is such that the said piece can be adjusted from a position in which its outlet is horizontal as shown in full lines in Fig. l to one in which its outlet is in- Specification of Letters Patent.

Serial No. 316,922.

clined at about forty-five degrees as indicated by dotted lines 9 in the same figure. To adjust"tl1e inclination from the latter to the vertical position indicated by the dotted lines it the connecting piece is first detached and then replaced with its curved portions in a reverse position to the original. Any convenient pivots i such as pivot screws at the ends of the connecting piece may be employed for securing it to the outlet.

The sides a" of the frame outlet are vertically disposed and parallel to each other and the sides (Z of the connecting piece are also vertically disposed and parallel to each other. The sides of the connecting piece snugly engage the sides of the frame outlet but this engagement is sufliciently free to permit the connecting piece to be adjusted.

By adjusting the bar 0 toward or away from a horizontal line drawn through the pivots 2', the bar may be adjusted to take up wear and the like.

The bar 0 is horizontally disposed and extends between the side walls a of the outlet.

By the above described construction an unimpeded passage is obtained throughout the whole range of adjustment.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is 1. The combination with a stove outlet flue having two parallel side walls, a top wall having its outer surface curved to coincide with an imaginary segment of a cylinder and a bottom bar having its outer surface curved to coincide with said segment, of a flue connecting piece having two parallel walls which snugly engage the parallel walls of the outlet flue and are pivoted on an axis forming the center of the imaginary cylinder, said piece also having curved inner surfaces which are parallel to the curved surfaces of the outlet flue top wall and bar, said bar being adjustable toward and away from one of the curved surfaces on the connecting piece.

2. A combination as defined in claim 1 in which'the :tlue piece is removable and re versible.

In testimony whereof we have signed our names to this specification.

HARRY JAMES YATES. CORNELIUS HEGGIE.
